- Imagine that you are training to run a half-marathon and so every week you have 2 intense days, 3 light days, and 2 rest days. On your intense days you run 16 km, on your light days you run 5 km, and on your rest days you do not run. How would you model your miles run per day as a random variable? (Hint: probability distribution)Grace Floral Shop sells several types of roses for all occasions. It is known that 43% of the roses that is sold by Grace Floral Shop are Eden Roses. 12 roses are ordered to put in a bouquet(i) Define the random variable for this situation and list its values (ii) Stating its parameter(s), what is the probability distribution of this variable? (iii) State the conditions that influence your choice of distribution.A racing car consumes a mean of 100 gallons of gas per race with a variance of 64. If 44 racing cars are randomly selected, what is the probability that the sample mean would be greater than 98.8 gallons? Round your answer to four decimal places.

- Find the expected value for the random variable whose probability function graph is displayed here AP 0.5- 0.4- 0.3- 0.2- 0.1- 0- 1 2 34 5determine whether the random variable X has a binomial distribution. If it does state the number of trials n. If it does not, explain why not. Twenty students are randomly chosen from a math class of 70 students. Let X be the total number of student absences. Part 1 The random variable -does -does not have a binomial distribution Part 2 Choose the statement that explains why X does not have a binomial distribution, more than one may apply -The Number of trials is not fixed -There are more than two possible outcomes for each trial -The probability of success is not the same for each trial -The trials are not independent -X does not represent the number of successes that occurRandom Variables - Question 5 Please solve with simple probability rules
- What are the differences between the two types of random variables in statistics? B i U Font Family AAA = in O 0Game of chance: A player rolls a fair six-sided die. If outcome of a roll is an odd number, the player wins as many dollars as there are dots on the top face . Otherwise, the player looses 4 dollars. Let the random variable X be profit (amount won or lost) per game. Make a probability distribution table for the random variable: amount won or lost. Find the Expected value of the experiment Use Law of Large numbers to interpret the meaning of the Expected value If a person plays 100 times, how much he expects to win/loose?
